"HENRY CORDES, OF SIOUX FALLS, SOUTH DAKOTA.

EXTENSION TABLE.

Application filed March 13, 1924. Serial No. 699,004.

To all whom it may concern:

Be it known that I, HENRY CoRDEs, citizen of Prussia, Germany, residingat Sioux Falls, in the county of Minnehaha and State of South Dakota,have invented certain new and useful Improvements in Extension ,Tables,of which the following is a specification. Thisinvention relates tocertain new and useful improvements in extension tables, and the primaryobject thereof is to provide automatic means for latching the extensionsin extended position.

A further object of the invention, is to provide improved means forslidably mounting the extensions so as to permit same to be easily andquickly moved into and out of extended position.

The invention still further aims to provide means for attaining theabove objects, of simple, compact and economical construction andreliable in operation.

The invention has still further and other objects, which will be laterset forth and manifested in the course of the following description.

In the drawings:

Figure 1, is a bottom plan view of the invention, one of the leavesbeing in extended position;

Figure 2, is a section on line 22 ure 1;

Figure 3, is a section on line 33 ure 1;

Figure 4, is a section on line 44 of Figure 1.

In proceeding in accordance with the present invention, a centralstationary or fixed top member 1 is employed, the ends of which arepreferably bevelled downwardly and inwardly. A pair of spaced cross bars2 and 3 are secured to the under face of member 1 at the center thereof.End rails 4 and 5 are secured at their ends to the respective legs 6 and7, at points spaced below the member 1, while side rails 8 are alsoconnected at their ends to the legs at points spaced below the member 1.

The extensions or leaves 9 and 10 are provided with end rails 11, which,when the leaves are in contracted position. seat on the end rails 4, theinner ends of the leaves being beveled to engage the beveled ends of themember 1, when the leaves are extended.

The leaf 9 is provided with a pair of spaced metal strip guides 12, thelatter. havof Figof Figing attaching wings 13 and being formed withspaced straight parallel slots'14 and 15 the inner ends of which latterare curved downwardly, the slot 15 having a forwardly extended lower end16 which forms a latching end.

The end rails 4 and 5 have mortises to receive the tenoned ends of atudinal bars 17, which latter are spaced below the member 1 and with theside rails 8, support theleaves in contracted or housed position, asshown in Figure 3.

The leaf 10 has a pair of guides 18 similar to guides 12 and which aresecured to the leaf by attaching wings 19. The pairs of guides 12 and 18are slidably engaged with the bars 17 on opposite sides of the latter,as depicted in Figures 1 and 12. The guides 18 have slots 20 and 21 withlatching ends 22 for the latter slots, as in the instance of the guides12.

Rods 23 and 24 are connected at their ends to the bars 17 and extendthrough the respective slots 20 and 21 of the guides 18,

while pins 25 and 26 extend through thepair of longi- In operation, theleaves in housed or contracted position are disposed as shown to theleft of Figure 2 and in Figure 3, and wherein same are engaged with thecross bars 2 and 3 have their inward movement restrict- 25 ed thereby,the cross bars having beveled edges so as to engage the beveled edges ofthe leaves 9 and 10, the rails 11 engaging on top of the rails 4 and 5.

. When the leaves are to be extended, same I are pulled outwardly, therods 23 and 24, 25 and 26 controlling the movements of the guides 12and.18, and causing the latter and thereby the leaves to move verticallyas the curved ends of the respective slots of the guides enter intoengagement with the rods. This movement of the guides causes the heels29 thereof to engage and move the latches 28 inwardly and the latterupon the curved ends of the slots reaching the bottoms of the latter,will move outwardly and cause the latching ends 16 and 22 of the slotsto be entered by the rods 23 and 26, with the result that the latchesexert pressure on the heels29 and 30 so as to hold the beveled edges ofthe member 1 and the leaves 9 and 10 in close engagement.

To rest-ore the leaves to contracted or housed position, same are firstmoved outwardly, depressing the latches and causing the rods 26 or 23 tobe disengaged from the latching ends 16 and 22 of the slots, whereuponthe outer ends of the leaves are tilted and moved inwardly whereby theguides and therewith the leaves are caused by the slots and rods or pinsto move to the housed position depicted in the drawings.

What is claimed is:

1. In an extension table, legs, a central member fixed to the legs, endand side rails fixed to the legs and spaced below the central member,spaced cross bars depending from the central member, leaves having depending end rails formed to seat on the end rails of the central member,spaced longitudinal bars depending from the central member, a pair ofspaced guides carried by each leaf and each having a pair of superposedslots with downwardly curved ends having latching terminals, therespective pairs of guides being disposed on opposite sides of thelongitudinal bars, rods connected to the longitudinal bars and extendingthrough the slots of the inner pair of bars, pins connected to thelongitudinal bars and to the side rails and extending through the slotsof the outer pair of bars, said guides having heels, and spring pressedlatches carried by the end rails and engaging the heels of the guides tourge the latter inwardly and thereby the leaves so as to hold the latterengaged with the' ends of the central member.

2. In an extension table, legs, a central member fixed to the legs, endand side rails fixed to the legs and spaced below the central member,spaced cross bars depending from the central member, leaves havingdepending end rails formed to seat on the end rails of the centralmember, spaced longitudinal bars depending from the central member, apair of spaced guides carried by each leaf and each having a pair ofsuperposed slots with downwardly curved ends having latching terminals,the respective pairs of guides being disposed on opposite sides of thelongitudinal bars, fixed members extending through the respective slotsto support the guides, heels on the guides, and spring pressed latchescarried by the end rails and engaging the heels to hold the leavesagainst the ends of the central member. I

In an extension table, a central membel, leaves, guides having heelsconnected to the leaves, means to mount the guides to effect movement ofthe leaves into and out of the plane of the central member, and springpressed latches for engagement with the heels to automatically urge theguides and thereby the leaves inwardly so as to hold the leaves engagedwith the central member.

4. In an extension table, a top member, a leaf, means to slidably mountthe leaf for movement beneath the top member and the plane thereof,compressible means spaced below the top member, and means carried by theleaf and which upon outward movement of the leaf engages and effectscompression of the compressible means and which upon release of the leafand expansion of the compressible means is automatically moved to slidethe leaf against the top member.

5. In an extension table, a top member, a leaf, means to slidably mountthe leaf for outward movement to enable same to be disposed in the planeof the top member, including a guide having a heel, and means forengaging the heel to automatically urge same inwardly and therewithslide the leaf against the top member.

6. In an extension table, a top member, a leaf, means to slidably mountthe leaf for movement beneath the top member and in the plane thereof,and power means for the leaf which upon outward sliding of the leaf haspower stored therein by engagement with the leaf and which power whenthe leaf is in the plane of the top member is released to automaticallyslide the leaf inwardly against the top member.

In testimony whereof I affix my signature.

HENRY CORDES.
